Steganography enables individual to attain privacy by providing efficient techniques to hide data. The term steganography derives its existence from ‘Johannes Trithemus’ literary work titled “Steganographia”. It can be applied to several digital medium such as text, image, audio and video. Research work is going on to improve the performance metrics so that a large amount of data can be hidden by...
Random texts have wide applications in day-to-day life. The most basic use of random text is in CAPTCHA generation. CAPTCHA is an abbreviation of Completely Automated Public Turing test to tell Computers and Humans Apart. It is a test that only humans can pass but current computer systems cannot. CAPTCHA protects web services from attack of codes that are automated to fill forms and overflow the servers...
Encryption for the compressed video stream has attracted the attention of many researchers within past few years. Due to exponential growth of digital multimedia contents over the network, their secure transmission over the network is a serious concern. Security and performance are two main peculiarities of any digital multimedia encryption algorithm. This paper presents an indexed chaotic sequence...
Casting a vote and counting votes both by electronic means constitutes Electronic Voting System. Creating an electronic voting system requires the use of robust voting mechanism that is relatively complex to design. In this paper we present a concept of electronic voting system which ensures authentication, authorization and accounting. Approach collects information from UIDAI and uses this information...
Detecting circular objects over digital images have received considerable attention from industries for applications such as detection of pellets in pelletization plant, target detection, inspection of manufactured products etc. Several algorithms were proposed in past few years to detect circular features. One powerful approach for circle detection is the Circular Hough Transform and its variants...
Circle detection over digital images has received considerable attention from the computer vision community over the last few years devoting a tremendous amount of research seeking for an optimal detector. Circle detection algorithms which were proposed till now have some limitations. One major limitation is detection of false circles in image. An efficient method of detecting false circles, called...
Steganography has become one of the most robust technique to transmit secrete or sensitive information between parties by concealing the information in some file which may appear to be of no importance to any interceptor. In this paper, we have used video file as the cover file and embedded the information in the frames where the scene has changed in the video sequence using the Least Significant...
Advancement in the digital media within the past few years has brought lots of new technology. Due to evolution of new techniques to transmit data over unsecured public network catches a serious attention of researchers regarding security and privacy issues. The transmission of multimedia data needed security in order to transmit over unsecured public network. In this paper we have proposed a video...
